AURISCOPE.

Specification of Letters Patent.

Patented May 27, 1913.

Application filed March 5, 1910. Serial N o. 547,450.

To all whom t may concern:

Be it known that I, HENRY L. DE ZENG, a citizen of the United States, residing at Philadelphia, county of Philadelphia, State of Pennsylvania, have invented a certain new and useful Improvement in Auriscopes, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to surgical devices which are adapted to enter orifices of various kinds in the body to illuminate normally hidden parts, and expose them to an operator so as to enable him to View and at the same time treat them.

The obj ect of my invention is to produce a simple and novel device of the kind specified which will make it possible to perform various operations, manipulations and treatments with the aid of a single device.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but for a full understanding of my invention and of its object and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawings, wherein:

Figure 1 is a longitudinal section through a device embodying my invention in a preferred form; Fig. 2 is a section taken at right angles to the plane of Fig. l, showing', however, only a fragment of the casing and the electric light mounted therein; Fig. 3 is a view looking toward the right in Fig. 1; Fig. l is a View similar to Fig. 3, the revoluble cap being, however, omitted and a p0rtion of the end wall of the casing being broken away; and Fig. 5 and Fig. 6 are end views, on a smaller scale, showing diiierent types of specula; and Fig. 7 is an end View of a modification, parts being broken away.

Referring to the drawings, A represents a casing, preferably though not necessarily cylindrical in form having one end closed by a wall B and having the other end open.

C is a speculum of any suitable form, the large end of which is telescoped within the open end of the casing and is frictionally held thereby. The speculum is made detachable so that it may be removed and replaced by one which is differently shaped; thereby permitting the device to be used in provided with two openings L and the eara nose or any other orifice, large or small, by providing interchangeable specula each of which is adapted to one particular orifice. Hthin the casing is a small electric light D which extends into the speculum and serves to illuminate the parts to be examined and treated. The supporting post D upon which the light is mounted may extend through the wall of the casing and be provided with terminals Z and d.

E is a rubber ybulb or other device for compressing air and it is Connected with the interior of the casing by a iiexible conduit e. The rear wall of the casing has therein three openings, F, G, and H, which, in the arvrangement shown, are arranged at 90 degrees apart about the center of the wall and at equal distances from the center.

I is a disk-like cap pivoted at its center to the central point of the rear wall of the casing in any suitable way as, for example, by means of a screw K passing through the rear wall so as to be revoluble therein and screwethreaded into the cap. The cap is M so located that in one angular position of the cap, the opening L will register with the opening Fl and the opening M will register with the opening H; while in a second posi.- tion of the cap the openings L and H will register as will also the openings M and F. The opening L is provided with a magnifying lens and constitutes the vision-opening in the cap. It will Abe seen that when the lens registers with the openingF in the casing, this latter opening'also constitutes a vision-opening while the registering openings M and H constitute instrument-receiving openings.

in using the apparatus, the operator looks through the lens and inserts the instrument through the instrument-receiving openings. The cap may then be turned so that the instrument may be produced through the opposite side. In this way the operator has a lnagniiied view of the part which is being treated and is able to reach this part either from the right or from the left. When the cap is turned into an intermediate position so as to bring the lens into registration with the opening G in the casing, the opening M in the cap is closed by a solid portion of the rear wall of the casing and the openings F and Gr are closed by portions of the cap so that the rear of the casing is closed and is provided with a magnifying window through which the part under treatment may be inspected. This is the condition in which the parts are placed when it is desired to massage the member under treatment, the bulb or other air supply device being manipulated. so as to produce air pressure within the casing.

The nozzles o-r mouths of the speculum may take any desired forms, Fig. 5 showing a speculum C having a round nozzle 0'; while Fig. 6 shows a speculum C2 having a nozzle 02 which is oval in cross-section. Each device may, of course be provided with a whole series of specula whose shapes and sizes differ to suit the various conditions under which the instrument is to be used.

In Fig. 7 I have shown a modification in which there is only one instrument-receiving opening, the lens being mounted in the wall of the casing instead of in the cap. Referring to this figure, N represents the end wall of the casing opposite the speculum and in this wall are two openings n and a. In the openinga is a lens O. P is a cap similar to the cap in the other form and having two openings therein p and 20 arranged so that in one position of the cap they will register respectively with the openings n and a. In this position of the parts the registering openings p and a constitute the vision opening while the registering openings a and 79 constitute the instrument-receiving opening. Vhen the opening p registers with the opening a the cap closes the opening n so that the instrument may be used for massaging.

While I have described in det-ail only a single preferred form of my invention I do not desire to be limited to the specific details' so illustrated and described; but intend covering all constructions and arrangements which fall wit-hin the terms employed in the definitions of my invention constituting the appended claims.

What I claim is:
